choose one over the other. One might be better for one type of application while the other might be a better fit‚ depending on the situation. They each have their own advantages which we will discuss in the following paragraphs. The first type of cable we will talk about is copper cabling. There are three main advantages in using copper cabling: (PoE‚ less expensive electronics and more flexibility). Power over Ethernet or PoE allows you to power phones‚ security cameras‚ Wireless Access Points (WAPs)

Silaba Mpasu Physical Networking Unit 6 Exercise 1 Connector Installations Twisted-pair cable On a TWISTED PAIR CABLE I chose to install an RJ-45. This is the standard Ethernet connector for most systems used today. I would first measure out the length of cable that I would need. I would then use a wire cutter to cut the length that I need‚ leaving enough room for corrections and to open the wire. I would then use wire strippers to remove a small piece of the outer most jacket. I would then choose

same bus. The star topology is a computer network connected via cables to a central system called a hub or switch there are no direct connections between any of the computers‚ although multiple hubs or switches can be added to increase the number of computers that may be connected to the network. A bus topology is the minimum complex network configuration it creates use of a single transmission medium called a coaxial cable. The star topology consists of shielded twisted pair wire (STP)

telephone-grade wire to extremely high-speed cable. The cable has four pairs of wires inside the jacket. Each pair is twisted with a different number of twists per inch to help eliminate interference from adjacent pairs and other electrical devices. Coaxial Television cable Coaxial cabling is difficult to install‚ it is highly resistant to signal interference. In addition‚ it can support greater cable lengths between network devices than twisted pair cable. Fiber-optic Connecting networks between

Chapter 3 Review Questions 1. What is different about the method used to boost a digital signal’s strength‚ compared with the method of boosting an analog signal’s strength? (D) A digital signal requires a repeater‚ which retransmits the signal in its original form‚ and an analog signal requires an amplifier‚ which increases the strength of both the signal and the noise it has accumulated. 4. What is the origin of the word “modem?” (B) Modulator/ demodulator 5. With everything else being
